Title: Improvements relating to hole sensing devices
Filed: 1964-10-16
Abstract: 1,023,898. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 16, 1964 [Oct. 23, 1963], No. 42241/64. Heading G4M. A sensing pin 6 is moved towards a perforated record 1 by the action of a spring 11 and a reciprocating frame 5. If a hole is present, latch 15 causes interposer 14 to rotate clockwise until end 21 engages shoulder 23, the interposer remaining in this position until near the end of the downward movement of frame 5 when it is able to swing clockwise part of the way to its contact closing position, at the same time pin 6 being projected further into the hole. As frame 5 moves upward to withdraw pin 6, end 21 slides over surface 24 and interposer 14 is rotated further in the clockwise direction to close contacts 27, 28. If a hole is also detected during the next downward movement of frame 5, contacts 27, 28 are opened, but are again closed during the upward movement as end 21 remains on surface 24. If no hole is sensed, end 21 remains, or is returned to the right of shoulder 23.

Title: Improvements in push-pull cable with plastic lined casing
Inventor: GILMORE WILLIAM JOHN
IPC: F16C1/26
Filed: 1963-10-28
Abstract: 974,729. Bowden mechanisms. AMERICAN CHAIN & CABLE CO. Inc. Oct. 28, 1963, No. 42378/63. Heading F2K. [Also in Division B3] In an outer member of a Bowden cable comprising a self-supporting sheath of wire 21, Fig. 5, wrapped helically, with successive coils contiguous, about a tubular liner 22 of plastics material, e.g. nylon, high density polyethylene, or P.T.F.E., the nominally uniform bore 23 of the liner has inwardly deformed portions 24 along its length which provide bearing surfaces of relatively small area for the sliding support of an inner member 25. The bearing surface 24 is a continuous helix, the cavities 26 between the turns of this helix serving to retain a lubricant. Wire of rectangular or parallelogrammic cross-section may be used. In a method of making the outer member, a plastics tube 12, Figs. 1 and 3, is fed axially between a pair of forming rolls, 13, 14, and simultaneously rotated at a speed such that its peripheral tangential velocity equals the feed rate of a wire 10 moving at right angles to the direction of travel of the tube 12. The shafts 15, 16, of the rolls 13, 14 are skewed relative to the tube axis by an angle equal to the desired helix angle of the coiled wire sheath. One corner of the wire is forced by the roll 14, which has an inclined peripheral groove 17, against the tube wall to produce a small permanent deformation of the latter. A pad 20 and the roll 13, which has a smooth periphery, turn the wire 10 about the tube 12 to form a parallel sided, helical coil. Other forming roll profiles may be used to obtain alternative helical forms. The linear speeds of the tube and wire, and the rotational speed of the tube, are controllable independently.
Patent GB-426354-A (GB)
Abstract: 426,354. Cables. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., and HUNTER, P. V., Hamilton House, Victoria Embankment, London. Oct. 10, 1933, No. 27901. [Class 36] A two-stage process for effecting the impregnation of the dielectric of a paper-insulated conductor comprises impregnating the previously dried laminated dielectric body of paper surrounding the conductor with a mobile insulating oil, removing from the insulated conductor, under conditions that do not result in evaporation of the oil absorbed by the paper, surplus oil unabsorbed by the paper, and subsequently impregnating the laminated dielectric with a relatively viscous insulating oil or compound. The conductor insulation is first dried and inserted in a vessel which is thereafter evacuated and into which, for example, transformer oil at 245 to 250‹ F. is drawn ; the impregnation process may be assisted by subjecting the oil to pressure or by evacuating the conductor from the interior or both. The vessel is then drained or the conductor removed and drained, after which the conductor is again subjected to vacuum in the vessel into which a more viscous fluid is then drawn ; for such impregnation, an oil of the same base, containing, if desired, rosin, may be employed at 245 to 250‹ F. ; pressure or evacuation or both may be applied as before. After cooling, the conductor is withdrawn and sheathed, for example, with lead. The dielectric may be dried by heat and evacuation prior to each impregnation treatment. The process may be applied to single or multi-core cables.

Title: A new or improved regulated power supply system, particularly for battery charging
Inventor: CARMICHAEL THOMAS FRAZER
IPC: H02J7/14
Filed: 1963-10-29
Abstract: 1,013,324. Charging batteries; machines with permanent magnets. SYNCHRO CORPORATION. Oct. 29, 1963, No. 42693/63. Headings H2A and H2H. [Also in Division G3] Voltage regulation.-A generator and regulator system for charging a battery includes a controlled rectifier connected so that it operates to short-circuit the load windings of the generator when the battery voltage exceeds a predetermined value. As shown a generator 11 has load windings 19, connected across a fullwave rectifier bridge 26 for charging a battery 12, and regulating windings 21 which are connected in series with the load windings 19. A silicon controlled rectifier 37 in series with the windings 19 and 21 forms a closed circuit therewith by way of diode 31, and a voltage sensing circuit constituted by a Zener diode 38 and a rheostat 39 is connected across the battery 12 and to the gate of the controlled rectifier 38. The load windings charge the battery through the rectifier bridge 26 until the battery voltage exceeds the threshold of the sensing circuit so that a gating current will begin to flow; when the gating power is sufficient, the controlled rectifier 37 will be rendered conductive during each alternate half-cycle to short circuit load and regulating windings and to reduce the charging current to zero. On intervening halfcycles, the controlled rectifier 37 returns to a blocking state, but the flux produced by the collapsing field in the windings saturates the generator poles and thus also reduces the charging current; the battery voltage then falls to a value insufficient to cause conduction of the controlled rectifier 37, and charging again commences. This cycle continues to maintain the battery voltage at a predetermined value. A second controlled rectifier may be provided so that equal regulation is obtained on both half-cycles of the generated voltage (Fig. 6, not shown), and the system may include a reactor to improve regulation at higher generator speeds (Fig. 7, not shown). In another embodiment, the regulating windings and the controlled rectifier are connected in series across the battery terminals (Fig. 8, not shown). Generator.-The generator comprises a rotor 15, constituted by a ring of magnetic material carrying ceramic magnets 17, and a stator 16 formed with poles each of which carries two separate windings, the load winding 19 and the regulating winding 21, the coils on each pole having a close magnetic coupling.

Abstract: 1,128,045. Washers; joint-making packing. NOUVEAUTES MECANIQUES & ELECTRIQUES NOMEL. 8 Oct., 1965 [29 Oct., 1964], No. 42795/65. Headings F2B and F2H. A composite sealing and self-locking washer comprises a generally annular resilient metallic core 6 having a substantially plane radially inner portion around a circular central orifice, the core being formed with teeth or biting edges on its opposite sides and a matrix of deformable sealing material, e.g. rubber or plastics, in which the core is embedded so that the central orifice is substantially radially aligned with a corresponding central orifice in the matrix, and the teeth or biting edges are fully embedded in the matrix, the matrix forming on one side of the radially inner portion of the core an annular bead 7, the thickness of which decreases radially outwards from a major thickness on the radially inner portion of the core. In use the washer is mounted on a rod 2 and compressed between a nut 8 and plate 1 and sealing material in the bead 7 is forced radially inwards to form a seal with the surface of the rod while being prevented from flowing outwards. In Fig. 1 the major thickness of the sealing material is of the order of two to three times that of the core, and the cross-section of the bead 7 is in the form of a right angled triangle with an angle of taper of 20 to 60 degrees at the vicinity of the radially inner edge of the washer. The washer may have a coating of constant thickness on one side. It can have an hexagonal outer periphery, indentations, or lugs, so that when compressed against a threaded rod it can be removed.

Title: Improvements in or relating to record changers
IPC: G11B17/16
Filed: 1965-10-08
Abstract: 1,111,890. Automatic record changer. WARWICK ELECTRONICS Inc. 8 Oct., 1965 [8 Oct., 1964], No. 42855/65. Heading G5R. In an automatic record changer for playing records of mixed sizes, a mechanism is provided which senses the size of the released record and controls the positioning of the stylus arm accordingly. The changer mechanism is driven by a drive pinion concentric with the turntable drive shaft which during record playing is adjacent a toothless portion of a control gear-wheel. When the stylus arm moves towards the centre spindle at the end of a record a link mechanism partially rotates the control gear to bring its toothed portion into engagement with the pinion. This commences the change operation which is completed before the control wheel is rotated one complete turn to its initial position. During initial rotation of the control gearwheel the stylus arm is raised and rotated to an " out " position and a record size sensing arm mounted on the pressure arm support is moved into line with the centre of the turntable. When the control gear has completed approximately half its rotation a conventional push off lever is actuated to release the next record, which depending on its size rotates the sensing mechanism by a predetermined amount. This movement sets the mechanism such that subsequently the stylus arm is lowered into the correct position for playing the record. Continued movement of the control'gear moves the stylus arm to the correct position, lowers it on to the record and moves the record size sensing mechanism to an out position. Means are also provided for sensing the end of the last record and switching off the record player.

Filed: 1962-11-14
Abstract: 980,711. Multi-stage evaporators. VERKSPOOR N.V. Nov. 14, 1962 [Nov. 17, 1961], No. 43057/62. Heading BIB. In an evaporator divided by partitions 2 into a number of flash chambers connected in series by channels 4 between the lower ends of the partitions and the bottom of the evaporator, wherein the liquid flows in succession through the chambers which are maintained at decreasing pressures, the upper boundary of each channel is formed by a substantially horizontal plate 3 which is inclined upwardly at the downstream end thereby forming a diffuser to ensure stable flow of the liquid. The other end of the plate is preferably also inclined upwardly. Stability of liquid-flow is further increased by providing, at the bottom of each channel, a transverse rib 7 which causes turbulence and the formation of bubbles. Guideplates 8 are mounted in each chamber to prevent the formation of mist. The vapours pass through openings 12 and are condensed on pipes 9; and the condensate is withdrawn through pipe 13. The apparatus may be used for the distillation of sea water, and also for the evaporation of strongly-foaming solutions.

Abstract: 917,270. Veneers; treating wood. GENERAL FLOORING CO. Inc. Dec. 16, 1960, No. 43360/60. Class 145. A wood member or veneer 24 is stretched and stress-relieved by passing it one or more times between rollers 12 and 18, the larger roller 18 being preferably formed of a rubber product and the veneer being fed by belts 20 and 22. Voids 32, 34 are thus created by partial separation of the fibres from one or both surfaces to about the middle of the thickness and the veneer is expanded in length beyond the length which it would have if completely saturated with water, so that the voids provide ample space for swelling of the fibres and prevent buckling in use.

Abstract: 897,724. Waste heat steam boilers. VORKAUF, H. Dec. 16, 1960 [Nov. 3, 1960], No. 43418/60. Class 123(2) In an installation for generating steam by means of the heat of blow gases from steel-making converters 2 which each discharge into an associated chimney 1 lined with steam generating tubes, the gases flowing from the chimney into a downpass 4 locating evaporator. Superheater and economiser surfaces 5, the gas cooling surfaces of all the chimneys and downpasses are connected to a common steam and water drum 3, but only the cooling surfaces of the chimney and downpass receiving heat are connected to the water circulatory circuit from the drum. Thus, immediately prior to and during the blow period of a converter, water is supplied to the cooling surfaces of its associated chimney through a pipe 9 leading from a multi-way valve 8, the valve receiving water from a circulatory pump 7 which draws it from the drum 3 through a pipe 6. Branch pipes lead from the pipes 9 to the respective convection-heated surfaces 5. The blow periods of the converters are so timed that the generation of steam is continuous. In a modification, all the chimneys discharge gases into one downpass containing convection-heated surfaces which are supplied continuously with water from the pump.

Filed: 1969-09-08
Abstract: 1281373 Removable coating for metal SCM CORP 8 Sept 1969 44361/69 Heading B2E [Also in Divisions C3 and C4] Metals to be heated to 1850-2300‹F are coated with a removable protective composition comprising comminuted inorganic material containing MgO, SiO 2  and Al 2 O 3 ; boric acid; oxides of nickel, arsenic, and/or chromium; and a liquid binder carrier (see Divisions C4-C5). The comminuted material may be a frit, and the composition may also include clay and/or a feldspar. The composition is used to give a temporary protective coating during high-temperature working of metals, particularly steels. In Example I an aqueous suspension of silica, china clay, boric acid, talc, nickel oxide and arsenic trioxide is spray-coated on to stainless steel-clad lowcarbon steel which, after drying, is heated to 1960‹F; on cooling again the coating spontaneously spalls. In Example II an aqueous emulsion of a polyacrylate and a pine resin containing two frits and petalite is dip-coated on to a stainless steel rod which is dried and heated to 1925‹F; the coating spalls on cooling. A similar result is obtained in Example III by dip-coating a stainless steel billet with a solvent solution of polybutyl methacrylate containing mineral spirits, aluminium stearate, a frit, and feldspar, heating to 2300‹F, and cooling, and in Example IV using a composition of vinyl-toluenated-alkyd resin, xylene and/or naphtha, two frits, and petalite.

Abstract: 939,040. Drilling machine details. T. D. WILLIAMSON Inc. Dec. 29, 1960 [Jan. 14, 1960; Oct. 13, 1960], No. 44613/60. Class 83 (3). [Also in Group XXIV] Apparatus for drilling a hole in a fluid pressure main without interrupting the flow, comprises a housing mountable on the main, a drilling spindle in the housing, means for feeding the spindle in response to relative rotation between the spindle and housing, which includes a slipping coupling to allow a greater rate of feed during movement of the spindle towards the work, than the actual drilling feed. The apparatus comprises a housing 10, Fig. 2, a drilling spindle 11 connected to a bush 17 rotatable in the housing, having a drill 12 secured thereto, a non-circular driving shaft 15 carried in a similar shaped bore 16 in the spindle and a feed nut 19 rotatable on the spindle. Nut 19 carries spring-urged balls 25 at 24 which engage in dimples in a member 22 keyed to spindle 11, thus forming a friction clutch. In operation, housing 10 sealed at 32, 33 against escape of fluid from the main, is screwed into a flange 10a, Fig. 1, and the latter is bolted to a valve 35 carried by a branch 36 on main 37. Shaft 15, along with spindle 11 is rotated by e.g. a motor 38, and clutch 22, 24, rotates feed-nut 19 at the same speed, thus feeding drill 12 up to main 37. As drilling commences, the clutch will slip, thus reducing the feed rate. Balls 25 may be replaced by projections fixed to clutch part 24, and parts 22, 24, can be made to reciprocate relative to each other. An adaptor for securing the apparatus to different sized valves may be provided for connecting to housing 10. In a modification, Fig. 5, spindle 11 has a thread 50 which engages with spring- urged balls 51, to provide the drill feed or the balls may be provided in the spindle, with the thread in housing 10. In a further modification, Fig. 7, spindle 11 is rotated by a handle 70 carried by a non-circular portion 71 on the spindle and a sleeve 73 screwed to housing 10, is axially fixed relative to the spindle by a thrust bearing 74, and a nut 72. An adjustable spring- urged plunger 76 in the handle engages depressions 75 in the sleeve so that on rotation of the handle, sleeve 73, and drill 12 will be axially fed until the drill engages the main, whereupon handle 70 will slip, and the feeding rate will be reduced. Housing 10 has a scale 79, which, when read in conjunction with the end of sleeve 73, indicates the depth of cut. The depth of cut is indicated in Fig. 2, by a graduated dip-stick 40.
